Question

I’m developing website where I need to execute one code at particular time.

Which is faster and better choice to write Cron Job or to use JavaScript Timing Event
or something similar or JavaScript

Answer 1

You are asking a question about two completely different things.

Cron job is based on the server, JavaScript (unless you are using NodeJS) is based on the client. Depending on whether this is a task that:

• must be performed and cannot be relied on the client (eg. the data is sensitive), or
• can depend on the client execution (which means the browser window should remain open and the JavaScript should be enabled),

choose Cron (1) or JavaScript (2) respectively.

It is really like a comparison between apples and oranges. Unless you will tell us whether you want orange juice or apple pie, we won’t be able to help you more. Just remember that Cron is for more reliable server-side task execution, and JavaScript timeout is per-user (or rather per-client), less reliable execution.
